DS-User F1 Help for GUI (Context-Sensitive) : Select Restore Performance Options (Windows DS-Client)
 
Select Restore Performance Options (Windows DS-Client)
This dialog box allows you to make some optional performance configurations. In general, you should use the defaults unless you have a high performance environment and the backup selected for restore is very large.
 
Maximum pending asynchronous I/O for a file
This is the maximum I/O operations the DS-Client will queue for each file during the restore process.
Use DS-Client’s settings
(Default) Uses the setting in the DS-Client Advanced Configurations > Category: Performance > Parameter: MaxPendingIOPerFile.
Use specific value
You can override the default and set a custom value that only applies for this backup set.
• This option is intended for high performance backup environments. You must be able to test the different settings to determine the optimal value.
• This is only useful if the target storage containing the backup data is fast and efficient enough to take advantage of the increased I/O.
• WARNING: Slower storage might suffer performance drops if this value is increased too much.
DS-System side read threads
This setting affects the DS-System side of the process. It instructs the DS-System how many files to read simultaneously for this restore process.
Use DS-Client’s settings
(Default) Uses the setting in the DS-Client Advanced Configurations > Category: Performance > Parameter: MaxRestoreReadThreads.
• Note: The actual value used maybe limited for some special backup sets.
Use specific value
You can override the default and set a custom value that only applies for this backup set.
• You must be able to test the different settings to determine the optimal value.
• WARNING: Slower storage might suffer performance drops if this value is not properly set.
